Tip Calculator Calculator
Tip amount, total bill, and per-person split for restaurant bills
Last updated:
What this calculator computes
The tip calculator splits a restaurant bill into the tip amount, the new total, and the per-person share when the bill is divided across a group. Inputs are the pre-tip bill amount, the desired tip percentage (15%, 18%, 20%, or any custom value), and the number of people splitting the bill. The calculator returns the tip in dollars, the grand total including tip, the per-person total, and the per-person tip portion — useful when a group wants to round up the tip per person rather than computing it on the bill total. Tipping conventions vary widely by country and context: in the US, 18–20% is the customary range for sit-down restaurant service, with 15% as a floor for adequate service and 25%+ for exceptional service; tipping is nominally optional but practically expected because servers' base wages are below the federal minimum and most income comes from tips. UK and EU restaurants typically include a 10–12.5% service charge on the bill (sometimes labelled "discretionary" but functionally automatic), so additional tipping is light. Australia, Japan, and most of East Asia have no tipping culture at all, with tipping sometimes considered impolite. The calculator does not encode local conventions but accepts any tip percentage so it works for any cultural context. It also handles tax-exclusive bills (US) and tax-inclusive bills (UK/EU/AU) — in jurisdictions where tax is added to the bill before the tip, the tip is conventionally calculated on the pre-tax subtotal rather than the tax-inclusive total.

The formula
Formula
tip = bill × (tip% / 100) total = bill + tip per_person = total / people
Worked example
When to use this calculator
Use this calculator at restaurants, bars, ride-shares, and any other service interaction where you need to compute a tip amount, add it to the bill, and (optionally) split the total across a group. The most common cases are sit-down restaurant bills (where 18–20% is the US norm), takeaway and delivery orders (where 10–15% is more typical), bar tabs (often $1–2 per drink rather than a percentage), hairdressing and personal care (15–20% in the US, 10% in the UK), and ride-share apps that prompt for tip in the app. The calculator's per-person split is most useful for casual group dining where everyone pays the same share regardless of what they ordered; for itemised splits use a separate per-item bill divider. The calculator does not handle tax-exclusive vs tax-inclusive bills explicitly, so US users tipping on a tax-exclusive subtotal should enter the pre-tax figure to match standard practice.
Common input mistakes
- Tipping on the post-tax total. In the US, restaurant tax is added to the bill before the tip is calculated, but the conventional tip is on the pre-tax subtotal. Tipping on the post-tax total inflates the effective tip by 2–10% depending on the local tax rate — equivalent to leaving a 22% tip when intending 20%. Some restaurants pre-print suggested tip amounts based on the post-tax total, which is technically incorrect but common.
- Using a percentage tip on top of an automatic service charge. UK and EU restaurants routinely add a 10–12.5% "discretionary service charge" to the bill, which functions as an automatic tip; adding another 15–20% on top doubles the gratuity. Always check the bill for an existing service-charge line before applying a percentage tip, and either remove the auto-charge or skip the additional tip.
Frequently asked questions
How much should I tip in the US?
US restaurant convention is 18–20% on the pre-tax subtotal for sit-down service, with 15% as a floor for acceptable service and 25%+ reserved for exceptional. Bartenders are typically tipped $1–2 per drink, takeaway 10–15%, and delivery 15–20% plus an extra few dollars for difficult conditions. The convention exists because the federal "tipped wage" is $2.13/hour (state minimums vary), so most server income comes from tips rather than base pay.
Should I tip on the pre-tax or post-tax bill in the US?
The traditional convention is to tip on the pre-tax subtotal, since tax is a government charge unrelated to service quality. In practice many people tip on the post-tax total because it is the larger printed number on the bill, which inflates the effective tip rate by the tax percentage (typically 5–10%). Either practice is socially acceptable; the calculator accepts whichever subtotal you enter.
How do tipping conventions differ by country?
US: 18–20% expected at sit-down restaurants. UK: 10–12.5% service charge often automatic; rounding up bill is fine if no charge included. EU continental: 5–10% acceptable, often included as service compris in France. Japan and most of East Asia: no tipping; can be considered impolite. Australia and New Zealand: no tipping required, occasional rounding up acceptable. Always check the bill for an automatic service charge in any country.
Can I tip in cash if the bill is paid by card?
Yes — tipping in cash directly to the server bypasses card-processing fees and any pooling rules the restaurant applies, so the server keeps a higher share of the tip. Some pooled-tip restaurants require all tips to go through the central pool regardless of payment method; others let cash tips go directly. From the customer's perspective the total cost is the same; from the server's perspective cash is often preferable when allowed.
How do I split a bill unevenly between people?
For uneven splits, use a per-item method: total each person's individual orders, add proportional shares of any shared items (appetisers, bottles of wine), and apply the tip percentage to each person's share separately. The simple per-person split mode in this calculator assumes everyone pays the same. That is the right model for casual group dining where the bill is roughly even across orders. For date-night or business meals where one person ordered a steak and another a salad, calculate shares item-by-item and pool the tip proportionally to each share.
